OIL-CUP COVER.

Application filed November 11, 1919. Serial No. 337,171.

To a whom it may concern Be it known that I, SAMUEL C. Hoax, a citizenof the United States, and a resident of Hlkinsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Oil-Cup Covers, of which the following is aspecification.

My invention relates to oil-cup covers and similar devices, and it hasfor its object to provide a novel device of the character designatedthat shall be simple and inexpensive to manufacture and strong anddurable in construction.

In the acco-mpz-inying drawing, Fig. l is a side View, partially insection and par tially in elevation, of a portion of a machine structureprovided with a cover constructed in accordance with my invention, andFig. 2 is a plan view of the cover shown in Fig. 1.

Heretofore, oil-cup covers have been made of single pieces of metalattached to the machines for which they were intended. being generallyformed of cast metal, and have not readily lent themselves to adaptationfor machines of dilferent types.

My invention is adapted for use on any machine or mechanism where it isdesired to provide an opening for the purpose of inserting oil, waste orother materials or to obtain a view of the interior workings of themachine.

A base member is formed, preferably by stamping, so as to fit closelyover the portion of the machine having the opening which it is desiredto cover, this base member having an opening therethrough surrounded byan upwardly struck flange. A cover, also preferably formed of pressedmetal, is fitted over said last-mentioned opening and is preferablyprovided with a peripheral flange extending down over the flange on thebase member, thus providing a tight closure. The cover member ispivotally mounted on the base member and a spring is associated with thepivot in order to maintain the cover member tightly closed, under normalconditions.

For a more detailed understanding of my invention, reference may now behad to the drawing wherein a machine 1 only a portion of which is shown,is provided with a base member 2 which has an opening 3 therethroughthat is surrounded by a flange 4, the member being attached to themachine 1 by means of screws 5. A covert, formed of pressed metal orother suitable material, is provided with a flange 7, fitting over theflange 4 of the member 2 when the cover is closed. An extension 8 of thecover serves as a means for raising it. A pin 9 connects the cover 6 tothe base member 2 by means of the flanges of both members. A spring 10is positioned on the pin 7 and causes the cover 6 to close and stayclosed unless subjected to outward pressure. The raised position of thecover is indicated by broken lines in Fig. 1. 7

Although I have shown the base member 2 so formed as to be tightlyseated on a machine portion having a cylindrical contour, it mayobviously be shaped to conform to any desired portion of a machine,irrespective of its contour, provided that the difference between theradii of the contact surfaces of the machine element 1 and the basemember 2 is not too great. The base member 2 has its greatest rigiditynear the flange 4t and its greatest flexibility at its outer edges,wherefore the flexibility of the base member 2 may be increased byincreasing the distances between the flange 4t and the outer edges ofthe base member 2.

Furthermore, although I have shown the member 2 attached to the machineby screws, it may be attached in various other ways, as by being clampedaround a portion of the machine.

It will be obvious to those skilled in the art that my invention issusceptible of additional changes and modifications without departingfrom the spirit thereof and may be used for a great variety of purposesother than those I have mentioned. Therefore, I desire that only suchlimitations shall be placed thereupon, as are imposed by the prior artor are specifically set forth in the appended claims.

I claim as my invention 1. The combination with a flexible base memberhaving an opening therein bounded by an upstanding substantially annularflange, a pin positioned in said upstanding flange, and a coverpivotally mounted upon said pin, of resilient means for maintaining thecover in a closed position.

2. The combination with a flexible arcuate base member having an openingtherein bounded by an upstanding substantially annular flange, a pinpositioned in said member, and a cover pivotally mounted upon said pin,of resilient means mounted upon said pivot pin for maintaining saidcover in a closed position.

3. In an oil cup, the combination with a slightly flexible base memberhaving an opening therein and provided with a rela tively narrowupstanding substantially annular flange portion around said opening, apin positioned in said flange portion, and a cover having flangeportions and pivota'lly mounted upon said pin, of a spring mounted uponsaid pivot pin for maintaining said cover in a closed position.

at. The combination with a machine element having a curved surface andhaving an opening therein, of a base member adapted to materially changeits curvature to conform to the surface of said element and having anopening therethrough provided with an exterior upstanding flangetherearound, and a cover member pivoted upon said exterior flange andadapted to conform thereto and to tightly close the opening in said basemember.

The combination with a machine element provided with an opening therein,of a composite closure for said opening embodying a flexible base memberfixedly attached to said element and surrounding said opening having anopening therein bounded by an exterior upstanding substantially annularflange portion and a cover-member pivoted upon said flange portion andadapt-- ed to close the opening in said base member,

In testimony whereof, I have hereunto subscribed my name this 1st day ofNov, 1919. V

SAMUEL G. HOEY.
